Minimally invasive interventional therapy usually refers to the diagnosis and treatment of diseases using interventional devices such as puncture needles and catheters under the guidance of fluoroscopy, CT and other imaging equipment, and is an emerging discipline that has flourished since the 1970s. Minimally invasive interventional therapy has become one of the three major treatment systems alongside with internal medicine and surgery. She is an emerging discipline, full of vitality. The surgeon punctures the human skin to form tiny orifices or feeds interventional devices through physiological cavities to perform various minimally invasive interventional operations and procedures, without the surgeon’s hands directly touching the patient’s lesion. This is different from traditional surgery. Therefore, it is characterized by less trauma, faster postoperative recovery, definite efficacy and fewer complications. For some diseases that are highly traumatic and risky to treat with conventional surgery, interventional therapy can often be addressed simply and effectively. The range of diseases treated by minimally invasive interventions is wide, so to speak, from head to toe and from inside to outside, which I will introduce to you and share together in future articles.
